att_abstract={{Content Centric Networking (CCN) is a new paradigm that
addresses the gap between the content-centric needs of a
user and the current widespread location-centric IP network
architecture. In this paper, we propose a hybrid content centric
architecture based on our pub/sub enhancement to CCN,
Content-Oriented Publish/Subscribe System (COPSS). Our
hybrid architecture (hybrid-COPSS) addresses both the need
for incremental deployment of CCN and also elegantly combines
the functionality of content centric networks and the
efficiency of IP forwarding. Our architecture integrates IP
multicast to achieve forwarding efficiency by taking advantage
of shortest path routing. To overcome the lack of interdomain
IP multicast, hybrid-COPSS uses COPSS multicast
with shortcuts as an overlay and IP multicast as the underlay
to achieve inter-domain COPSS multicast.
To demonstrate the benefits of our hybrid-COPSS architecture,
we study its applicability for online gaming, which
typically requires low latency. We use a gaming trace in
our lab test-bed and microbenchmark the forwarding performance
and queuing for a pure COPSS (representative of a
pure CCN) based network versus hybrid-COPSS. Also, a
large scale simulation (parameterized by the microbenchmark)
on a representative ISP topology was used to evaluate
the response latency and aggregate network load for the
multi-player online gaming scenario. Our preliminary results
show that hybrid-COPSS performs better in terms of
response latency compare to pure COPSS in a single domain.
In a multi-domain environment, hybrid-COPSS can
significantly reduce inter-domain traffic while causing only
a small increase in the average response latency.}},
